CLAMP FOR BATTERY-ELECTRODES.

SPECIFICATION forming part of Letters Patent No. 773,249, dated October 25, 1904.

Application filed June 27, 190d. Serial No. 214,236. (No model.)

To all whmn it may concern:

Be it known that I, EBEN G. Donen, a citizen of the United States, and a resident of I class of batteries in which the negative plate consists of copper or other oxid properly molded, as in a type of battery now well known and to which reference is made in United States patents to James W. Gladstone, dated June 2, 1903, and November 3, 1903.

My present invention is designed more particularly to remove certain objections incident to the use of clamps detachably connected to the frame or hanger in the manner described in Patent No. 742,856, dated November 3, 1903, just referred to. In the device described in that patent the spring-clamp is detachably connected with the side rods of the frame or hanger by a slot-and-pin connection so arranged that the clamp is caused to lock or engage with the pin by a vertical movement. It sometimes happens with this form of device that the clamp becomes disengaged through striking upon some obstruction in the act of inserting the frame or hanger into the battery-jar. The more immediate object of my present invention is to avoid this objection to the use of the device described in the prior patent and to provide,'further, a means wherebya clamp detachably connected with the side rods or frame shall be securely held against accidental detachment in any manner.

To these ends my invention consists, primarily, in the combination with the frame or hanger and the cooperating clamp detachably secured thereto by a pin-and-slot catch, of supplemental locking devices adapted to secure the parts against reverse movement or in the direction to permit the head of the pin to slip through the eye from which the slot extends.

My invention consists,further, in constructing the device so that the clamp shall become engaged with the pin by a movement of the clamp in a horizontal direction instead of a vertical direction to cause the headed pin to enter the slot in the clamp.

My invention consists, further, in the details of construction and combination of parts more particularly described and then specified in the claims.

In the accompanying drawings, Figure 1 is a side elevation of the hanger equipped with the device constructed in accordance with my invention. Fig. 2 is a plan of Fig. 1, the hanger-rods being shown in cross-section. Fig. 3 is an elevation of the clamp detached from the side rods. Fig. 4 is a section of the same on the line 00 m, Fig. 3, and looking in the direction of the arrow, showingthe locking device in position to permit the clamp to engage the pin on the side rod. Fig. 5 is an end view showing the locking device in position to lock the clamp against detachment.

D indicates the battery-electrode, which may be of copper oxid or other material, and E E indicate the side rods of the frame or hanger, which side rods, as described in the prior patent above referred to, are suitably equipped at their upper ends with means for securing them to the cover of the battery-jar.

Inasmuch as my invention is not confined to any particular form of cover, battery-jar, or opposite electrode used in conjunction with electrode D, I have not illustrated such devices in the accompanying drawings.

I indicates the back clamp or support se- I cured to the side rods and against which electrode D is pressed by means of able clamp O.

K K indicate the headed pins, which project from the side rods E E and with which the slots and eyes P p P p in the clamp O cooperate for attachment and detachment of said clamp.

The clamp may be caused to engage the pins the detachon both side rods E by a horizontal movement. This construction is indicated in Figs. 3, 4, and 5. In this case the eye or opening P is formed in the upturned end of the clamp and receives the head of the pin when the clamp is moved horizontally to cause the shank of the pin to enter the slot P, and the clamp is locked against reverse movement. which will permit it to bedisengaged at either end by means of the sliding bolt A, which slides vertically in a guide formed by the turned-up end of the clamp and has an opening in its edge which cooperates with the eye or opening l", and which when the sliding lock stands in the position shown in Fig. at will permit the head of the pin to enter the eye or opening P, but when moved to position indicated in Fig. 5 will lock the parts against movement in a direction to permit the clamp to become disengaged.

ltis preferableobviously to form the parts so that look A shall be held by friction or spring of the parts in locking position.

The term horizontally or horizontal is hereinbefore used to mean a movement transverse to the ordinarymovement of the frame or hanger in inserting the hanger into the battery-jar, which in this form of battery usually contains a liquid and must therefore be maintained in an upright position.

What .1 claim as my invention is 1. in an electric battery, the combination with an electrode-supporting frame or hanger, of a cooperating clamp dotachably secured to the frame by a pin-aml-slot connection and supplemental means for locking the clamp against a reversemovement, or in a direction to disengage the pin. and clamp.

2. In an electric battery, the combination with an electrode-supporting frame or hanger, of a cooperating clamp detachably connected to the frame by a pin-and-slot catch adapted to engage and disengage by a movement transverse to the line of movement of the frame or hanger in inserting or withdrawing the same from the battery jar or cell.

3. In an electric battery, the combination with an elect'rod e-supporting frame or hanger, of a cooperating spring-clamp detachabl y connected at its ends with the frame or hanger by a pin-and-slot catch, and means mounted upon said clamp for locking the same against reverse movement, as and for the purpose described.

i. Iln an electric battery, the combination with an electrode-supporting frame or hanger, of a spring-clamp detachably connected with the frame or hanger by a pin-and-slot connection adapted to engage and disengage by a horizontal movement, and means for locking the clamp against horizontal movement.

5. In an electric battery, the combination with an electrode-supporting frame or hanger, of aelamp detachably connected to the frame or hanger by a pin-and-slot connection at one end, a pin-and-slot connection at the other end and means at the latter end for locking the clamp in position where it is engaged.

6. In an electric battery, the combination with an electrode-supporting frame or hanger, of a clamp detachably secured to the side rod thereof by a pin-and-slot connection, and a catch or lock engaging with said pin to prevent reverse movement of the clamp upon the pin.

Signed at New York, in the county of New York and State of New York, this th day of June, A. D. 1904.

EBEN G. DODGE.
